12 VOLT 30 AMP AUTOMATIC
P/No. SC030
SOLAR CHARGE CONTROLLER

IMPORTANT SAFETY INFORMATION
Please read this manual thoroughly before use and store in a safe place for future reference.
WARNING
• Please read these instructions completely prior to installation.
• Lead acid batteries can be dangerous. Ensure no sparks or flames are present when
working near batteries. Eye protection should be used. If mounting on a vehicle follow
all manufacturers’ instructions.
• Given sufficient light solar panels always generate energy even when they are
disconnected. Accidental ‘shorting’ of the terminals or wiring can result in sparks
causing personal injury or a fire hazard. It is recommended to cover the front face
of the panel(s) with a soft cloth to block incoming light during installation.
• For use with 12V (nominal) solar panels.
• For indoor, out of weather use only.
• Do not exceed the total limit of the solar controller (360W/30A)

INSTALLATION
The charge controller is designed to be mounted flush with the wall. Flush mounting
requires a rectangular cutout in the mounting surface with sufficient space (50–75mm)
depth behind, to accommodate the controller and wiring. The charge controller may
also be mounted to the wall without making a cutout. This is the quickest and easiest
mounting procedure, however, the controller will be raised from the wall.
WIRING DIAGRAM
Connection Procedures (please refer to the connection diagram above)
1. Once the controller has been properly mounted select either Gel or Wet modes on the unit.
2. Connect the solar panel positive side to the charge controller “ARRAY” positive (+)
with a suitable wire. Be careful not to short circuit the solar array.
3. Connect the solar panel negative side to the charge controller “ARRAY” negative (-)
with a suitable wire.
4. Connect the battery positive side to the charge controller “BATTERY” positive (+)
with a suitable wire.
5. Connect the battery negative side to the charge controller “BATTERY” negative (-)
with a suitable wire.

Please pay close attention to the following wire specifications
WIRE SIZE
Refer to the “WIRE SIZE” chart below to determine the minimum size wire needed for
each connection. When using heavy stranded wire, you may need to divide the ends into
two groups and straddle the screw on the terminal block.
WIRE SIZE – INSTALLATION
NOTE: Any variation of wire size or length will affect the performance of the charge
controller.
OPERATION
Once properly mounted and connected, the charge controller will start charging
immediately given adequate solar power. The 12 Volt 30 Amp Solar Charge Controller is
based on a three stage charging algorithm; Bulk Charge Mode, Constant Voltage Mode
and Float Mode.
Battery condition is indicated by the LED lights. The controller will indicate the battery
condition in three states: GOOD (green), FAIR (yellow), LOW (red). Please refer to label.
Please note the charge controller is not able to start the charging process if the initial
battery voltage is less than 3 volts (+/- 0.3).
CHARGING STATUS INDICATOR L.E.Ds
The top 3 LED indicator lights show the charging status of the charge controller.
The red LED indicates solar power available.
ON: indicates solar panel properly connected and solar power supplied within parameters
OFF: indicates no power available or insufficient voltage to activate controller.
The blue LED indicates the charge controller is in “Bulk Charge or absorption” mode.
The green LED indicates “Charge Complete” which means the battery is fully charged and
the charge controller is in float mode

BATTERY CHARGE LEVEL INDICATOR L.E.Ds
The bottom 3 LED indicator lights show the batteries level of charge.
The green LED indicates the battery voltage is greater than 12.5V.
The yellow LED indicates the battery voltage is between 11.5V and 12.5V.
The red LED indicates the battery voltage is less than 11.5V.
The red LED will blink if battery is disconnected from the unit. The charge controller will
not function if not connected to both the battery as well as the solar array. Testing may not
be performed while the charge connector is unhooked from one or both of the batteries or
solar array.
When Solar Power is weak as well as during the night the charger will turn off the
charging LED.
MAINTENANCE
The following maintenance is recommended to be performed every three months:
1. Ensure all wire connections are sound and free from corrosion. Tighten terminal block screws
for both the solar array as well as the battery terminals.
2. Visually check the solar array and battery wiring for signs of overheating, damage, and
cracking. Replace any wires showing wear with new wires of the same gauge.
3. Verify each LED status to ensure match with specifications using a voltmeter.

FREQUENTLY ASKED QUESTIONS
Q. Why wont my battery charge?
A. Solar panel may be sized incorrectly. A panel with a larger output is required. You may add
on to existing panels by wiring the additional in parallel with the existing panel.
Usage may be too high. The battery is being drawn upon at a faster rate than the panel
is able to produce. A secondary battery may be used, by physically switching the batteries
out and allowing one battery to supply power while the other is being charged.
Battery may be too small. In this case it may appear the battery is not charging however
it is the reserve that is depleting too quickly. A battery with a larger capacity may be
required. A secondary battery may be used, either by physically switching the batteries
out and allowing one battery to supply power while the other is being charged or using a
battery isolator. A second battery may also be added to the existing battery by wiring the
additional battery in parallel to the existing battery. The charge controller only needs to be
connected to one of the batteries in this case.
The battery may be bad. Small level of charge or discharge will greatly affect the battery
voltage. Battery needs replacing.
Wires may be incorrectly hooked to the charge controller. Ensure the wires are connected
in parallel to the controller and to the correct terminals.
Q. Why does my solar panel have no output?
• The solar panel may be seriously affected by the angle of the panel with regards to the
sun, and environmental factors. Ensure the surface is clean and free of dust and build
up. A clean, damp rag may be used to clear the panel of dust. Do not use soap or
solvents of any kind. Cloudy conditions will affect the output of the solar panel.
• Wires may be incorrectly hooked to the charge controller. Ensure the wires are
connected in parallel to the controller and to the correct terminals. Please refer to the
Connection Procedures portion of this manual.
